Area of Science:

  • Neurosurgery
  • Plastic Surgery
  • Biomaterials Engineering

Background:

  • Craniofacial reconstruction demands precise anatomical understanding for optimal results.
  • Patient-specific implants (PSIs) manufactured using advanced software offer solutions when autologous tissue is insufficient.
  • Polyether ether ketone (PEEK) is a biomaterial with potential applications in reconstructive surgery.

Purpose of the Study:

  • To evaluate the clinical utility and outcomes of PEEK-PSIs in craniofacial reconstruction.
  • To assess the safety, efficacy, and patient satisfaction associated with PEEK-PSI use.
  • To determine the feasibility of PEEK-PSIs for complex bony defect repair.

Main Methods:

  • Retrospective chart review of 6 patients undergoing craniofacial reconstruction with PEEK-PSIs.
  • Utilized computer-aided design (CAD) and computer-aided manufacturing (CAM) for virtual implant planning and fabrication.
  • Data collected included patient demographics, operative indications, surgical time, hospital stay, defect size, implant cost, and manufacturing time.

Main Results:

  • Mean patient age was 46 years; indications included cancer, congenital deformities, and infection.
  • Mean surgical time was 3.7 hours, with a mean hospital stay of 1.5 days.
  • No major or minor complications were observed during a 4-year follow-up period, with high patient satisfaction noted.

Conclusions:

  • PEEK-PSIs are effective for reconstructing complex calvarial defects, demonstrating a low complication rate.
  • The use of PEEK-PSIs in this series resulted in good functional and aesthetic outcomes.
  • PEEK implants show significant promise for cranial reconstruction, warranting further investigation.
